KDG4V333C30XVMUH760

The KDG4V333C30XVMUH760 proportional valve belongs to the KDG Non-feedback Proportional Valves series and is manufactured by Vickers for hydraulic automation that relies on electrical modulation of oil flow. A 24 V DC coil voltage supplies the solenoid with standard control power, while a coil resistance of 7.3 Ω sets the steady-state current drawn from the drive card. Coil inductance is 20 mH, a value that reduces current ripple and stabilizes spool movement during rapid command changes. The solenoid can be energized continuously because the duty rating is 100 % ED, preventing thermal overload during extended cycles. Maximum coil current is limited to 1.6 A, so power electronics can be sized accurately for safe operation. A DIN 43650 connector provides the electrical interface, allowing quick removal for service without disturbing the cable. A plain manual override permits direct spool shifting during setup or in an emergency. The valve reaches 90 % of a commanded step in 25 ms, giving responsive flow adjustment for dynamic systems.

At the hydraulic side, the valve delivers a rated flow of 30 L/min through the A and B ports, supplying sufficient oil volume to medium-sized actuators. Maximum operating pressure at the A, B, and P ports is 350 bar, defining the upper limit for system pressure, while the T port tolerates up to 210 bar to accommodate elevated return-line conditions. The mounting interface follows ISO 4401-03 (NFPA D03), so the unit bolts directly to standard subplates without adapter blocks. An IP65 ingress protection rating seals the coil and connector against dust and low-pressure water jets, enabling use in wash-down or outdoor areas. Physical dimensions of 237.998 mm in length, 48.26 mm in width, and 86.36 mm in height allow compact integration inside manifold banks or machine frames. Together, these pressure, flow, interface, and enclosure features define the operating envelope and mechanical fit of the KDG4V333C30XVMUH760 within industrial hydraulic circuits.
